Need advice ASAP......

Well yesterday I had DirecTV installed and the installation went flawless. But i have now noticed on my Toshiba 50H82 that Ihave what appears to be little black moons on the sides of my TV screen, a total of 3 on each side, I mean they are basrely visible but they look like there is som kind of interference or something. It is there on local cable, DirecTV, even when I watch a DVD. Does anybody have any ideas what could be causing the problem. I have the ant cable comming from the wall to a Monster Cable surge then out of the surge then into a diplex that splits the signal into sat and cable. The sat runs straight to the Hughes sat Reciever then from the Hughes out to the tv in S-Video, and analog audio. Then the cable side of the diplex runs straight into the tv. I also have audio jacks from the tv going into my Technics A/V Reciever for surround (for regular tv) if i want. The Panasonic player has Component (YRG) into the tv, the Toslink into my Technics. NOthing has changed in the setup except for the addition of the DirecTV reciever. I might call Toshiba and have them send someone out to take a lok at it if ai cant figure t out on myself. Any help I would appreciate.
